Description
RELATED APPLICATIONS
This application claims the benefit of Korean Patent Application
No. 10-2013-0071945, filed on Jun. 21, 2013, in the Korean
Intellectual Property Office, the entire content of which is
incorporated herein in its entirety by reference.
BACKGROUND
1. Field
Exemplary embodiments of the present invention relate to an
adhesive display panel, including an input connector and an
adhesive display system that includes the display panel and the
connector, In particular, exemplary embodiments of the present
invention relate to an adhesive display system attachable to and
detachable from a wall surface that is capable of being integration
to form a large screen by connecting a plurality of transparent
flexible display panels.
2. Description of the Background
A display device is device that, as part of its function, displays
image signals from external inputs. Representative display devices
may include televisions, computer monitors, personal digital
assistants (PDAs), and a variety of widely available smart
devices.
Typically, a high-definition flat display module such as an organic
light-emitting display (OLED) panel, a liquid crystal display (LCD)
panel, or a plasma display panel is used in the display device.
These recent developments in display technology have made thinner
display panels possible.
However, it is difficult to realize the advantages of thin display
panels since space-consuming auxiliary hardware components, like
those used to fix the display panel and arrange wiring, must be
installed around the display panel. Additionally, as the size of
the display panel increases, the cost of manufacturing the display
panel increases dramatically due to expenses involved in wiring,
making it costly to implement a large panel.
New technology is demanded to implement a light, thin, and
integrated electronic information system. To this end, research has
been actively conducted into system on glass (SOG) technology for
integrating hardware components on a single substrate. The SOG
technology allows various hardware elements for voice processing,
display, data processing, storage, input/output, and communication
to be integrated on a glass substrate. In current SOG technology,
semiconductors are integrated on the glass substrate. Consequently,
a display panel may include not only a driving circuit, but also a
memory and a central processing unit (CPU). When current SOG
technology is applied, a module in which a circuit is installed may
be unnecessary. Therefore, display panels incorporating SOG
technology may be very thin and all computing functions may be
integrated in a flat panel.

of ordinary skill in the art may easily implement the present
invention.
FIG. 1 schematically illustrates an adhesive display panel
according to an embodiment of the present invention.
An adhesive display panel 100 includes a display unit 110 and an
adhesive layer 190.
The display unit 110 includes a display part D, as shown in FIG. 2,
having a light-emitting device and a driving circuit for driving
the display part D. The display unit 110 represents a region where
data is received and light is emitted by driving the display part
D. The display unit 110 may be flexible and transparent.
The display unit 110 may be one of a cathode ray tube (CRT), an
electro luminescence (EL) device, a vacuum fluorescent display, a
plasma display panel, a (LCD), a thin film transistor-liquid
crystal display (TFT-LCD), an organic light-emitting diode (OLED),
and an electrophoretic display.
As noted above, the display unit 110, may be flexible. In other
words, the flexibility indicates that the display unit 110 may be
bent by an external force. Since the adhesive display panel 100 may
be flexible, the adhesive display panel 100 may not be damaged
while being attached to or detached from a surface, such as a
wall.
The adhesive layer 190 includes an adhesive material. The adhesive
layer 190 may include any material for integrating homogeneous or
heterogeneous solids by bonding surfaces of the homogeneous or
heterogeneous solids. More specifically, a thermoplastic adhesive
such as vinyl, acryl, or synthetic rubber may be used as the
adhesive material. The adhesive layer 190 may have such adhesive
strength that the display unit 110 is kept bonded to an external
wall surface. The adhesive layer 190 may be thin and include a
transparent material. Thus, it does not affect the flexibility and
transparency of the display unit 110.
Although FIG. 1 illustrates that the adhesive layer 190 constitutes
one layer, the adhesive layer 190 may be a thin film obtained by
applying the adhesive material on one surface of the display unit
110.
The adhesive display panel 100 may be attached to a surface, such
as an indoor or outdoor wall. The wall surface is not limited to an
inner wall surface/outer wall surface of a building, and may
include any spatial region on which a display can be bonded and
installed. For example, the adhesive display panel 100 may be
attached to a windscreen of a vehicle.
A conventional display may be installed and fixed by means of a
stand or a screw, and is supplied with power and data through a
wire. Due to the wiring and various tools for fixing the display,
the display panel may not be installed on a wall surface even
though a display panel is thin. On the contrary, the adhesive
display panel according to exemplary embodiments of the present
invention may adhere to an attaching surface without using
additional installation hardware, so that the advantages of the
small thickness and light weight of the display panel may be fully
realized. Since the adhesive display panel 100 is transparent and
flexible, the display may be viewed from both sides when the
adhesive display panel 100 is attached to a transmissive surface
such as glass, and the adhesive display panel 100 may not be
damaged when being attached to or detached from the attaching
surface.
FIG. 2 is a diagram illustrating a plan view of the adhesive
display panel 100 according to an exemplary embodiment of the
present invention.
Referring to FIG. 2, the adhesive display panel 100 includes the
display part D and a non-display region N arranged at a perimeter
of the display part D. Image signals are displayed on the display
part D, and various display devices such as organic light-emitting
devices, LCD devices, or electrophoretic display devices may be
arranged in the display part D. The display part D will be
described in more detail later. Although an active matrix (AM)-type
panel is exemplarily used as the flexible display panel in an
embodiment of the present invention, the present invention is not
limited thereto. A passive matrix (PM)-type panel may also be
used.
Various driving circuits and wirings for supplying image signals to
the display device of the display part D may be arranged in the
non-display region N.
Referring to FIG. 2, an electrode power supply line 131 for
supplying electrode power ELVSS to the display part D is arranged
in the non-display region N. A scanning circuit unit 133 for
transferring a scanning driving signal to the display part D is
arranged in the non-display region N, and a data circuit unit 135
for transferring a data driving signal to the display part D is
also arranged in the non-display region N. In addition, a driving
power wiring unit 137 for supplying driving power ELVDD to the
display part D is arranged in the non-display region N.
The electrode power supply line 131, the scanning circuit unit 133,
the data circuit unit 135, and the driving power wiring unit 137
may be arranged together on a substrate on which the non-display
region N is formed, instead of being arranged on an additional
substrate or a flexible printed circuit film.
A processing unit 140 connected to respective wirings of the
electrode power supply line 131, the scanning circuit unit 133, the
data circuit unit 135, and the driving power wiring unit 137 is
arranged in the non-display region N. The processing unit 140
includes a memory and a central processing unit (CPU) so that the
adhesive display panel 100 may perform a computing function. That
is, the adhesive display panel 100 is capable of inputting and
editing information through processing unit 140, whereas a
conventional display panel simply outputs visual information.
The processing unit 140 serves to connect the wirings of the
electrode power supply line 131, the scanning circuit unit 133, the
data circuit unit 135, and the driving power wiring unit 137 to
wirings of pad units Pb, Pl, and Pr. When receiving data and power
from an external device through the pad units Pb, Pl, and Pr, the
processing unit 140 converts the received data and power and
transfers the converted data and power to the respective driving
circuits 131, 133, 135, and 137. Additionally or alternatively, the
processing unit 140 may simply provide a connection between
wirings. For example, when receiving the driving power ELVDD
through the pad units Pb, Pl, and Pr, the processing unit 140 may
simply transfer the received power to the driving power wiring unit
137.
In the following description, the data received by the pad units
Pb, Pl, and Pr may include any data needed to display an image on a
display panel. Since the adhesive display panel 100 is provided
with the processing unit 140 incorporating the processor, the
adhesive display panel 100 may receive unprocessed image data and
convert the data into a vertical synchronization signal Vsync, a
horizontal synchronization signal Hsync, a data enable signal, and
an image data signal DATA_in applied to the data circuit unit 135.
Therefore, the data received by the pad units Pb, Pl, and Pr may be
image data itself.
The pad units Pb, Pl, and Pr may also receive the vertical
synchronization signal Vsync, the horizontal synchronization signal
Hsync, the data enable signal, and the image data signal DATA_in.
In this case, the processing unit 140 serves as a timing control
unit. The processing unit 140 receives the vertical synchronization
signal Vsync, the horizontal synchronization signal Hsync, the data
enable signal, and the image data signal DATA_in, and outputs, to
the data circuit unit 135, an RGB data signal obtained by
converting the image data signal DATA_in in accordance with the
structure of data circuit unit 135 and a clock signal. The
processing unit 140 may output the RGB data signal to the data
circuit unit 135 according to a differential signalling method,
i.e. a low voltage differential signalling (LVDS) or reduced swing
differential signalling (RSDS) method. In the case of using the
RSDS method, six wirings for R, G, and B and two wirings for the
clock signal may be used.
The processing unit 140 may output, to the scanning circuit unit
133, an output enable signal for controlling an output of the
scanning circuit unit 133.
The electrode power supply line 131, the scanning circuit unit 133,
the data circuit unit 135, the driving power wiring unit 137, and
the processing unit 140 may be arranged together on the substrate
on which the non-display region N is formed, instead of being
arranged on an additional substrate or a flexible printed circuit
film. This technology of integrating all elements on a single
substrate is referred to as a system on glass (SOG) technology.
That is, utilizing SOG technology, the adhesive display panel 100
may be reduced in thickness and may allow integration of computing
functions in a single panel. In another embodiment of the present
invention, all the elements in the non-display region N may be
arranged in the display part D, utilizing SOG technology.
The pad units Pb, Pl, and Pr, in which terminals 139 are arranged,
may be disposed under the processing unit 140. The terminals 139 of
the pad units Pb, Pl, and Pr serve to receive and transfer inputs
from an external device, and are connected to the processing unit
140. The terminals 139 of the pad units Pb, Pl, and Pr are used to
supply power or data to the adhesive display panel 100. The number
of the terminals may vary with a type of the adhesive display panel
100. Although it is illustrated that the pad units Pb, Pl, and Pr
are respectively disposed at the bottom, the left, and the right of
the display panel, the positions of the pad units Pb, Pl, and Pr
may be changed.
In an embodiment of the present invention, the terminals 139 of the
pad units Pb, Pl, and Pr are connected to a terminal unit 530 of
connectors 500a and 500b described below (see FIG. 3). However, the
terminals 139 may also be connected to other external devices.
The various circuits, wirings, and terminals described above with
reference to FIG. 2 are merely exemplary elements arranged in the
non-display region N. That is, the various circuits, wirings, and
terminals of the non-display region N may be arranged in a
different manner from that of FIG. 2.
The non-display region N may occupy a minimal space in comparison
with the display part D. Alternatively, unlike the embodiment of
FIG. 2, the non-display region N may overlap the display part D so
that only the display part D is viewed when the adhesive display
panel 100 is viewed from above an upper surface of the adhesive
display panel 100, through the SOG technology.
Since the terminals 139 of the pad units Pb, Pl, and Pr are
connected to an external device, the adhesive display panel 100 may
receive data and power. The terminals 139 may be connected to the
clip-type connectors 500a and 500b. Clip-type connectors 500a and
500b may be configured to correspond to an attachment to each of at
least one of pad units Pb, Pl, and Pr.
FIG. 3 is a schematic diagram illustrating a connector according to
an embodiment of the present invention.
Referring to FIG. 3, the single-sided connector 500a may include a
hinge unit 510, a fixing unit 511, a connection unit 512, a wire
540, and a plurality of terminal units 530 provided to the
connection unit 512.
The hinge unit 510 connects the fixing unit 511 to the connection
unit 512, and serves as a rotating axis for changing an angle
between the fixing unit 511 and the connection unit 512. The hinge
unit 510 may supply each terminal unit 530 with data and power
received through the wire 540.
The fixing unit 511 forms a variable angle with the connection unit
512, and serves to fix the single-sided connector 500a so that the
terminal units 530 of the connection unit 512 are kept connected to
the pad units Pb, Pl, and Pr when the single-sided connector 500a
is connected to the adhesive display panel 100. That is, the fixing
unit 511 together with the connection unit 512 provides a clip-type
detachable structure for fixing the adhesive display panel 100. As
the fixing unit 511 and the connection unit 512 are opened or
closed, the terminal units 530 of the connection unit 512 may be
separated from or fixed to the terminals 139 of the pad units Pb,
Pl, and Pr.
The connection unit 512 contacts the adhesive display panel 100 to
supply data and power. The connection unit 512 includes at least
one terminal unit 530. The terminal units 530 may contact the
terminals 139 of the pad units Pb, Pl, and Pr of the adhesive
display panel 100 to supply data and power. More specifically, the
terminal units 530 may contact the terminals 139 to transfer the
driving power ELVDD, the electrode power ELVSS, and data for
displaying an image.
Although seven terminal units 530 are illustrated in FIG. 3(A), the
number of the terminal units 539 may be changed according to a type
of the adhesive display panel 100 and an amount of the data or
power to be transferred. Distances among the terminal units 530 may
be determined according to distances among the terminals 139 of the
pad units Pb, Pl, and Pr.
The hinge unit 510 may be supplied with power and data from an
external device through the wire 540. The hinge unit 510 transfers
the received power and data to the terminal units 530 of the
connection unit 512.
FIG. 3(B) is a diagram illustrating the double-sided connector 500b
according to another embodiment of the present invention. Referring
to FIG. 3(B), a pair of fixing units 511 and a pair of connection
units 512 are provided to both sides of the single hinge unit 510.
That is, the two connection units 512 oppose each other about the
hinge unit 510, and the two fixing unit 511 oppose each other about
the hinge unit 510. Angles between the fixing units 511 and the
connection units 512 may be independently determined. Power and
data transferred to the terminal units 530 of both the connection
units 512 may be independent. That is, the data transferred to the
terminal units 530 of the left-side connection unit 512 may be
different from the data transferred to the terminal units 530 of
the right-side connection unit 512.
The fixing units 511 and the connection units 512 may be connected
to different adhesive display panels. For example, the left-side
fixing unit 511 and the left-side connection unit 512 may be
connected to the first adhesive display panel 100 and the
right-side fixing unit 511 and the right-side connection unit 512
may be connected to a second adhesive display panel 100, so that
the first and second adhesive display panels 100 and 20 may be
connected to each other through the double-sided connector
500b.
FIG. 4 is a schematic diagram illustrating the connector 510a
connected to the adhesive display panel, according to an embodiment
of the present invention.
Referring to FIG. 4, the single-sided connector 500a of the present
invention may be connected to the lower-side pad unit Pb disposed
at the bottom of the adhesive display panel 100. Since the
connector 500a includes the seven terminal units 530 according to
the embodiment illustrated in FIG. 3, the single-sided connector
500a may be connected to seven terminals 139 of the lower-side pad
unit Pb. The single-sided connector 500a connected to the
lower-side pad unit Pb may be connected to a different location.
FIG. 4 exemplarily illustrates that the connection unit 512 faces
upward so that the terminal units 530 arranged on the connection
unit 512 electrically contact the terminals 139 of the pad unit
Pb.
The single-sided connector 500a may be connected to not only the
lower-side pad unit Pb but also the left-side pad unit Pl or the
right-side pad unit Pr. Alternatively, the connector connected to
the pad units Pb, Pl, and Pr may be the double-side connector
500b.
The single-sided connector 500a transfers power and data to the
adhesive display panel 100 through the terminal units 530 of the
connection unit 512. The terminals 139 of the adhesive display
panel 100 connected to the terminal units 530 of the connection
unit 512 may receive power or data according to a transmission
standard.
The single-sided connector 500a receives power that is to be
supplied to the adhesive display panel 100, from an external device
through the wire 540. The power received through the wire 540 may
include the electrode power ELVSS and the driving power ELVDD.
The single-sided connector 500a may receive data that is to be
applied to the adhesive display panel 100, through the wire 540.
The data to be applied to the adhesive display panel 100 may be an
image signal or a driving signal of the display panel. According to
an embodiment of the present invention, when the image signal is
transferred to the adhesive display panel 100, the processing unit
140 may convert the image signal into a signal to be applied to the
scanning circuit unit 133 and the data circuit unit 135 since the
memory and the CPU are included in the processing unit 140.
According to an embodiment of the present invention, the
single-sided connector 500a may receive data from an external
device 700 through a network 600. The network 600 may be a wired
network including the wire 540 and connecting the connector 500a to
the external device 700. Although a wired connection is illustrated
between connector 500a and external device 700, the device is not
limited thereto, and wireless connections are also possible. For
example an embodiment having a wireless connection may include an
integrated battery unit and be configured to accept data
wirelessly.
The adhesive display panel 100 may be connected to another adhesive
display panel 100 through the connectors 500a and 500b as
illustrated in FIG. 5. In the case of implementing a large screen
display by connecting a plurality of adhesive display panels 100,
data and power should be received from an external device to
provide for stable operations. In this case, the data and power may
be received from the external device 700 through the network
600.
In order to generate one image on the plurality of connected
adhesive display panels 100, a divider may be used to divide the
image by the number of the display panels. The external device 700
may serve as a divider for dividing the image to be displayed on
the plurality of adhesive display panels 100. In addition, the
external device 700 may externally perform a function of the
processing unit 140 of the adhesive display panel 100, or may serve
to complement the function of the processing unit 140.
Alternatively, the external device 700 may be a power supply
device. Any device that is capable of performing these functions
may be utilized as the external device 700.
FIG. 5 illustrates adhesive display panels that are connected to
each other according to an embodiment of the present invention.
Referring to FIG. 5, an adhesive display system 1000 forms one
image using the plurality of connected adhesive display panels 100.
The plurality of adhesive display panels 100-1 to 100-4 may be
connected to each other by the double-sided connector 500b. For
example, the first adhesive display panel 100-1 is connected to the
third display panel 100-3 by the double-sided connector 500b
through the lower-side pad unit Pb, and is connected to the second
adhesive display panel 100-2 by the double-sided connector 500b
through the right-side pad unit Pr. Each of the adhesive display
panels 100-1 to 100-4 receives power and data from the terminal
units 530 of the connector 500b to display an image. The wire of
the connector 500b may be connected to a back surface of the
adhesive display panel 100.
FIG. 5 illustrates four adhesive display panels 100-1 to 100-4, but
the present invention is not limited thereto. Therefore, a
plurality of adhesive display panels may be connected to each other
by the connectors 500a and 500b.
The adhesive display panel 100 of the present invention can be
attached to an outer wall or glass wall of a building, and thus can
be easily installed. Furthermore, by connecting the adhesive
display panels 100 to each other using the connectors 500a and
500b, a large screen display can be implemented. Moreover, since
power and data can be simply input to the adhesive display panel
100 by using the clip-type connectors 500a and 500b, complicated
wiring is not necessary. A person having skill in the art will
appreciate that this arrangement clip-type connectors is merely
exemplary, and the connectors can have different shapes and
arrangements based on the positions of the terminals and adhesive
panel displays.
